In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

Water is needed at mine sites for dust suppression, mineral processing, coal washing, and
hydrometallurgical extraction. For these applications, water is mined from surface water …

Iron-bearing nanominerals such as ferrihydrite, schwertmannite, and green rust behave as
metastable precursors leading to the formation of more thermodynamically stable iron …

Schwertmannite is a ubiquitous mineral formed from acid rock drainage (ARD), and plays a
major role in controlling the water chemistry of many acid streams. The formation of …

Mine stream precipitate collected from Ilkwang mine, Korea, contained high concentrations
of arsenic (As), while water collected from the same site had negligible As concentrations …

Mine tailings exposed to water and oxygen generate acid mine drainage (AMD) when the
neutralizing minerals are insufficient to buffer the acid produced by sulfide oxidation. Mineral …

Weathering of sulphide minerals produces a large variety of Fe-oxide-bearing ochreous,
varicoloured precipitates and efflorescences of variably soluble sulphate salts. These …

In acid mine drainage (AMD), precipitated schwertmannite can reduce the trace metal
concentration by adsorption and co-precipitation. With the geochemical changes in the …

In acid-mine drainage and acid-sulfate soil environments, the cycling of Fe and As are often
linked to the formation and fate of schwertmannite (Fe8O8 (OH) 8− 2 x (SO4) x). When …

Schwertmannite is an iron hydroxo sulfate secondary mineral (Fe 8 O 8 (OH) 8-2x (SO 4) x•
nH 2 O; 1≤ x≤ 1.75) that commonly precipitates in sulfate-rich acid and metalliferous …
